About This Game

In PlayIndex, games are the stocks.

Every price is driven by one number: how many people are actually playing that game right now. Live Steam concurrent player counts are pulled every 10 minutes and turned into a market you can trade. No fictional companies, no invented charts: when a game blows up on a Friday night, you watch it happen on the tape.

Build a portfolio out of games you think are about to catch fire, and sell before the hype fades.

Trade the player count

• Buy and sell anything on the board: fractional shares, so nothing is ever out of reach.

• Automate your exits: limit buys, take-profits and stop-losses trigger on the market scan while you're away.

• Read the chart: price and player history side by side, 1D/1W/1M/All ranges, average-buy and trade markers, and candlesticks once you've earned them.

• IPOs: new Steam releases debut on the board with an opening window. Get in before the price finds its level.

The market tells you why

• Market Events: every sharp move is logged and paired with the Steam headline that likely caused it: a free weekend, a big patch, a controversy.

• Live tape: a movers ticker and a running feed of what other traders are actually doing.

• News: aggregated headlines from across the top of the market, flagged when a story moved a price.

• Watchlist: star the games you're stalking and keep them one glance away.

Build a career

• Levels and XP: earned from every trade and milestone you hit.

• Badges and weekly objectives: rotating goals that pay out credits and XP, with Steam achievements to match.

• Cosmetics: unlock equippable titles, name colours, avatar frames, and full terminal colour themes for the whole interface.

Compete

• Global leaderboard: all-time net worth, with a public profile behind every trader on it.

• Monthly Seasons: a fresh ladder ranked on portfolio growth, not on who started first. Win one and wear it.

• Groups: private leaderboards for you and your friends. Settle who really reads the market best.

The City

Park your profits somewhere they can't crash. At Level 10 you unlock a savings account and the property market: buy lots in a city whose districts follow game genres, put up buildings, and hedge against a bad week on the board.

• Build: eight building types, three tiers each. Some pay rent every hour; others produce materials, cut your trading fees, lift the lots next door, or pay interest on your savings.

• The flea market: building materials are earned by playing, and players buy and sell them with each other on The City's own market.

• Facades: cosmetic building skins that drop as you play. They are real Steam Inventory items: trade them, or sell them on the Steam Community Market.

Stream it like a news desk

Streamer Mode opens a second, OBS-ready broadcast window styled like a financial news channel: live trade tape on top, movers ticker below, a banner chyron naming the game on screen, and a chart over your shoulder. Your camera fills the frame. Flip on chroma-key mode and the unused space keys out, so you composite like a real studio. Your balance, portfolio and orders stay on your private screen; the audience only ever sees the market.

Built to fit around your day

The market ticks every 10 minutes, so PlayIndex never demands a session. Check in, study the charts, make your moves, get on with your life. Come back after a few hours and a return digest totals the rent you earned and what moved while you were gone. A desktop Companion app keeps your portfolio glanceable while the game is closed, with tray alerts when a game you hold or watch makes a sharp move.

Interface available in English, German, French, Spanish, Portuguese, Polish, Turkish, Russian, Simplified Chinese and Japanese.
